An electron transport chain pumps across a membrane while transferring from one chemical to another. view available hint(s) an electron transport chain pumps across a membrane while transferring from one chemical to another. protons; electrons atp; atpase electrons; protons electron carriers; protons

The correct option is: protons; electrons

Explanation:

The electron transport chain contains a series of biomolecules that are involved in the transfer of electrons by redox reactions.

This process involves the transfer of electrons from an electron donor molecule to an electron acceptor molecule, resulting in the release of energy. Some amount of this energy is then used in pumping the protons across the biological membrane.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
